From my 9/23 email from Chabad.org
This rocked my world:
… “Rebbe [Menachem M. Schneerson] would frequently quote the Maimonidean adage: Each person should see himself as though the entire world is on a delicate balance, and with one deed, he or she can tip the scales.
It’s G-d’s world, He won’t let it falter. But He wants us to be His partners.
He gives us each the power to turn our world upright, to perfect it.
Every good act, every expression of kindness and love, acts like a thousand antibodies to neutralize the viruses of evil and germinate the world with holiness.
Let us each do our share. And then G-d will surely do His.”
